Display device

Abstract

A display device includes a display panel, a rear case, a printed circuit board (PCB), and a conductive adhesive member. The rear case includes a bottom plate and sidewalls. The bottom plate faces the display panel and the sidewalls are extended from the bottom plate along the display panel. The PCB includes a ground conductive layer and is electrically connected to the display panel. The ground conductive layer is exposed toward the bottom plate. The conductive adhesive member is disposed between the ground conductive layer and the bottom plate and electrically connects them. Accordingly, the PCB and / or its circuit components may be protected from static electricity, which may be discharged through the bottom plate.

Benefits of technology

[0006]In accordance with one or more embodiments of the present invention described herein, there is provided a display device (e.g., an LCD) that may reduce potential damage to circuit elements of a PCB caused by static electricity and thus may improve circuit reliability. For example in one such embodiment, the display device includes a display panel, a rear case (e.g., a receiving container), a PCB, and a conductive adhesive member. The rear case includes a bottom plate and sidewalls. The bottom plate faces the display panel, with the sidewalls extending from the bottom plate along the edges of the display panel. The PCB is electrically connected to the display panel and includes a ground conductive layer and an insulating layer covering the ground conductive layer, wherein the insulating layer has an opening through which at least a portion of at least a portion of the ground conductive layer is exposed to the bottom plate. The conductive adhesive member is disposed between the ground conductive layer and the rear portion of the bottom plate, to electrically connect the ground conductive layer to the rear case.

[0011]In accordance with an embodiment, the ground conductive layer, which is formed on the PCB and is electrically connected to the bottom surface, may reduce the potential for damage to the display device. For example, the PCB, including circuit components and conductive paths on the PCB, may be protected or have a reduced risk of damage due to static electricity generated during the manufacture, assembly, and use of the display device.

Problems solved by technology

The static electricity flows through metal circuit lines in the display panel or the PCB and results in failures, such as disconnects or shorting of the metal circuit lines.

Furthermore, the static electricity may cause electrical damage to circuit components, such as the timing controller.
